Condensed Cream of Mushroom Soup "Campbell's"

I got this recipe over here: http://www.deepsouthdish.com/2010/11/homemade-condensed-cream-of-mushroom.html and wasn't able to import it. I like to keep all my recipes in one place, but want to give credit where credit is due! What I like about this recipe is that what you end up with is "condensed" cream of mushroom soup, so it's ready for use in other recipes. Also, big point in it's favor is that it can be FROZEN but probably should not be pressure canned as it has dairy in it.
